For an adventure team looking to become a PVP team, that is a long stretch, however I can help you with a few things.

Charizard:

No reason to run triple fire moves, and since you're running Charizardite Y, run mainly Special Moves.

Special moves are indicated by this icon: Click to view special moves icon.

Azumarill:

Sad that you don't have huge power, but you can run a defensive set instead with Thick Fat and so-so EVs.

Replace hydro pump with Aqua Tail for slightly better accuracy and that it's a physical move, which can be run with Waterium Z. Make sure you use scald to fish for burns(30% chance) to hopefully tank better. Waterium Z can also be replaced with leftovers if you need passive recovery.

Leavanny:

Stick with miracle seed, use focus sash if you get it in conjunction with relearning Sticky Web move, given that you levelled Sewaddle to 31.

Replace all special moves with physical moves as you have a -sp.atk nature and your EV spread.

Sorry but I'm too lazy to detail the last 3, but you can always google Smogon and the respective Pokemon to find some competitive PVP sample sets for them and base off it to what you can manage.
